Fish-Hatching in a Current of Water. 113 



The moss, and any foreign substance, having 

 been removed, the attendant should use a 

 pair of pincers made of wire about the size of 

 knitting-needles, with the ends turned in a 

 circle with the opening about the size to 

 hold an egg, to pick out dead eggs. The 

 ova should be distributed evenly over the 

 gravel by using a feather from a goose or 

 turkey's wing. A little practice will enable 

 this to be done without touching the eggs, 

 simply by causing a current over them, as, 

 being but little heavier than water, they are 

 easily moved aboiit in it. One thousand eggs 

 can be hatched to the square foot of space in 

 the hatching-boxes, but double this space is 

 better, and after the fish are hatched, much 

 more room and an increased current of water 

 are required to do them justice. 



In a new fish-hatching institution lately 

 established by Livingston Stone, a mode 

 of hatching was adopted with success, which 

 greatly economizes space in the hatching- 

 race. The eggs were placed, 10 or 12 layers 

 deep, in baskets made of galvanized wire, 

 and the current was made to rise up through 

 them from below. The baskets were placed
